There are several JUnit assertion methods and they are all static methods defined in org.junit.Assert class. You can easily use them if you do import static org.junit.Assert.*;
- fail() - fails test
- assertNotNull(o) / assertNull(o) - assert if object is (not) null
- assertFalse(b) / assertTrue(b) - asserts if b is false / true
- assertEquals(a, b) - compares two objects using equals() method: a.equals(b)
- assertSame(a, b) - compares two objects using == operator: a == b
- assertArrayEquals(a, b) - compares two arrays
- assertThat(o, condition) - asserts that o satisfies the condition specified by an instance of org.hamcrest.Matcher
